The victim was part of a two-man crew assigned to replace 12 fused electrical cutout switches located on utility poles at a housing project.
  • Lineman Electrocuted after Contacting 7,200-Volt Cutout Switch on Utility Pole in Tennessee. FACE 90-26, (1990). A lineman was electrocuted when he contacted a 7,200-volt cutout switch on a newly installed utility pole. Just before the incident, the victim had climbed the utility pole, installed a cutout switch, and connected it (with a jumper cable) to a 7200-volt conductor that had not yet been energized.
  • Lineman Electrocuted When He Contacts a 7,200-volt Powerline While Installing a Guy Wire in North Carolina. FACE 90-27, (1990). A 30-year-old journeyman lineman was electrocuted when he contacted a 7,200-volt power line while installing a guy wire.

  • Request for Assistance in Preventing Electrocutions of Crane Operators and Crew Members Working Near Overhead Power Lines. Publication No. 95-108, (1995, May). Describes five cases (six electrocutions) that resulted from the hazards of operating cranes near overhead power lines and makes recommendations for preventing similar incidents.
  • Request for Assistance in Preventing Electrocutions During Work with Scaffolds Near Overhead Power Lines. Publication No. 91-110, (1991, August). Describes 13 deaths that occurred in six separate incidents when workers erected or moved scaffolds that came into contact with energized, overhead power lines, or when they contacted overhead power lines while using conductive tools or materials from scaffolds.
  • Request for Assistance in Preventing Electrocutions of Workers Using Portable Metal Ladders Near Overhead Power Lines. Publication No. 89-110, (1989, July). Describes six deaths that occurred because portable aluminum ladders, which conduct electrical current, came in contact with energized overhead power lines. The lack of compliance with existing regulations in the five incidents described suggests that many employers and workers may be (1) working unaware of these OSHA regulations, (2) misinterpreting the requirements of the regulations, or (3) failing to inform their workers about the dangers of using metal ladders around overhead power lines.
  • Request for Assistance in Preventing Fatalities of Workers Who Contact Electrical Energy. Publication No. 87-103, (1986, December). Prompt emergency medical care can be lifesaving for workers who have contacted either low voltage or high voltage electric energy. Immediate cardiopulmonary resuscitation (CPR) within approximately 4 minutes followed by advanced cardiac life support (ACLS) within approximately 8 minutes has been shown to save lives.
  • Request for Assistance in Preventing Electrocutions from Contact Between Cranes and Power Lines. Publication No. 85-111, (1985, July). Presents information on five cases which resulted in six fatal injuries involving crane-related electrocutions.

US Department of Health and Human Services (DHHS), National Institute for Occupational Safety and Health (NIOSH) Publication No. 2000-116, (2000, September). Also available as a 2 MB PDF, 334 pages. Reports that falls from elevations were the fourth leading cause of occupational fatalities from 1980 through 1994. The 8,102 deaths due to falls from elevations accounted for 10 percent of all fatalities and an average of 540 deaths per year. Between 1982 and 1997, NIOSH investigated 90 falls incidents that resulted in 91 fatalities.
• Maintenance Technician Drowns After Falling From a Turbine Support-Ring Platform at a Hydroelectric Power Generation Facility in South Carolina. National Institute for Occupational Safety and Health (NIOSH) Fatality Assessment and Control Evaluation (FACE) 9116, (1991). Two technicians left the basket to inspect the welds. Neither was wearing a buoyancy (life) vest, even though life vests were available at the site and the company required their use.
• Electrical Lineman Dies After Falling 35 Feet to the Ground from a Burning Aerial Bucket in South Carolina. National Institute for Occupational Safety and Health (NIOSH) Fatality Assessment and Control Evaluation (FACE) 9035, (1990). Standard employer practice required the use of common hydraulic hoses (without metal reinforcement) on any area of the boom or aerial bucket that might be placed near energized power lines. The mechanic told investigators that he knew he was installing the wrong type of hose, but did not understand the potential hazards involved. When the hose ruptured while the lineman was using the impact wrench, the spraying hydraulic fluid contacted the hot metal and ignited.

A 51-year-old worker (the decedent), a co-worker, and the employer were installing a TV tower at the side of a building housing the employer's business. As the workers were trying to stabilize the TV tower into the pre-dug hole, it fell and contacted one phase of a three phase 7200-volt overhead power line. The electrical current traveled from phase to ground, killing one worker and giving the co-worker a severe electrical shock.

• OSHA's requirements for locking type snaphooks on pole strap systems. OSHA Standard Interpretation, (1996, March 13).
